Supine Arm Lengthener



The supine arm lengthener promotes shoulder mobility and good upper body posture.

Set up

Begin lying on your back with legs straight and arms down by your sides.


Slowly reach one arm up over your head keeping your elbow straight until it is above your head, resting on the floor. Gently reach that arm higher, making it as long as possible without changing the position of your spine and hips. Hold for 5 seconds. Then return to the starting position and switch sides.


  • If you can’t bring your arm all the way over your head, you can put a pillow under your arm to support it and fill in the space between your arm and the floor.
  • Maintain a neutral spine – do not arch your lower back.
  • Draw your belly in as you reach.
